Abstract
A copper winding structure includes a first copper sheet having a first body, a first extending part and a second extending part located at two ends of the first body, respectively; and a second copper sheet having a second body, a third extending part and a fourth extending part located at two ends of the second body, respectively, the third extending part intersects with the fourth extending part such that the second body is partially overlapped; after the first copper sheet is stacked with the second copper sheet, the second extending part aligns with the third extending part, and the first extending part and the fourth extending part are located on the same side with respect to the second extending part and the third extending part.
